One of the neatest things about the Play Store is that, as long as you're signed in to your account on the web, you can install apps directly to your device without ever picking it up. Now, Google has integrated this functionality into Google+. If a user shares a link to an app on the Play Store, that friendly blue "Install" button will now be embedded directly in the post. A-like so:

This is a nifty new addition to Google+. Of course, the embeds don't include ratings, user reviews, or any of the other key information that everyone should probably at least glance at before installing apps on their devices. Still, if it's a trusted source, it's a cool way to save a few seconds. More than anything, it's just nice to see Google integrating more of it's products.
